Can anyone suggest an easy way to increase the font size of an entire document (including headers/footers) by a certain percentage? I know I can do it by going through word by word and setting the font size to the original font size multiplied by a factor, but this seems slow and tedious. Is there a better way?

I have a document that needs to print in different font size under different circumstances and I do not want to maintain two versions of it.

Any ideas?

TIA
